Ergonomic mouse

ABSTRACT

An ergonomic mouse has a sliding cap matching the curvature of a normal human palm. The sliding cap may be slid on the top of a hollow body to reach a desired operation position, then fine-tuned and anchored. Thus when the mouse is moved during operation, it can absorb reaction forces to avoid hurting the user&#39;s wrist and better meet ergonomic requirements.

FIELD OF THE INVENTION

The invention relates to an ergonomic mouse, and particularly to a mouse having a sliding cap pivotally mounted onto a hollow body and slidable thereon that may be fine-tuned and anchored to better meet ergonomic requirements.

BACKGROUND OF THE INVENTION

The typical mouse device has a track ball partially exposed on the outside. When the track ball rotates under a force, two wheels that are normal to each other located inside the mouse also rotate. Through optical detection, the rotation speeds of the two wheels are converted to moving distances on a set of coordinates. Hence when an electronic device is connected to the mouse, the cursor on the screen will move relatively from a start position to a destination position.

In order to suit the operation type and computer usage habit of different users, the mouse design is constantly being improved. Nowadays a wide variety of mouse selections are available on the market. Each has its unique functions and features.

Operation of the mouse mainly relies on the user's wrist. Moving the mouse for a prolonged period of time often results in physical pain to users, or even causes injury to the user's wrist. Although most mouse devices adopt an ergonomic design to prevent injury, they generally focus on the ergonomics of the palm for holding the mouse (namely to conform to the normal palm curvature), but rarely consider the ergonomics related to the moving of the mouse. As a result, many reaction forces are not absorbed. Injury to the wrist can still occur.

SUMMARY OF THE INVENTION

In view of the aforesaid problems, the primary object of the invention is to provide an ergonomic mouse. The mouse according to the invention has a sliding cap conforming to the common palm curvature of a human hand. The sliding cap is pivotally coupled to a hollow body and slidable on the top of the hollow body. The sliding cap may be moved to a desired operation position suitable to a user, and be fine-tuned and anchored on the hollow body. Then the mouse can absorb reaction forces while moving to avoid hurting the user's wrist. Thus it can better meet ergonomic requirements.

In order to achieve the foregoing object, the mouse according to the invention includes a hollow body and a sliding cap. The hollow body has a first port and a trough on the top, and a housing section in the interior. The sliding cap has a cap body, an axle and an elastic anchor member. The cap body has a boss running through the first port to pivotally couple the cap body on the top of the hollow body. The axle has two ends located respectively in the cap body and the housing section so that the cap body is turnable about the axle. The elastic anchor member corresponds to the trough to anchor the cap body relative to the hollow body. Hence after the cap body is slid to a desired operation position, it may be fine-tuned and anchored on the hollow body. When the mouse is moved during operation, it can absorb the reaction force to protect the user's wrist from injury. Thus it can better meet ergonomic requirements.

To make the sliding direction of the sliding cap more accurate, the invention further includes stub shafts pivotally located on the top of the hollow body and two opposite sides of the sliding cap to enable the sliding cap to slide forwards and backwards relative to the hollow body, or slide to the leftwards and rightwards, or slide forwards, backwards, leftwards and rightwards.

The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
